Hello, I currently have the script (reprinted at the end of this post), which works when calling a VBA macro (which accepts parameters in Excel). The problem however is when I modify the App.Run line to accept the input parameter objects that I have picked up from the command line instead of string literals (commented out in the code below). When I do this, I receive the following error.

Error: 13
Error (Hex): D
Source: Microsoft VBScript runtime error
Description: Type mismatch

How can I correct this (if possible)??

My script:

Dim app ' Application object handle
Dim wb ' Workbook object handle

dataFilePath = WScript.Arguments.Item(0)
macroName = WScript.Arguments.Item(1)
inputFilePath = WScript.Arguments.Item(2)
dataParam1 = WScript.Arguments.Item(3)

' Assign the application object handle to an Excel instance

Set app = CreateObject("Excel.Application")

' Ensure that the user isn't bothered by the temporary instance of Excel
app.Visible = False
app.DisplayAlerts = False

' Open the workbook containing the relevant macros to be run
On Error Resume Next
Set wb = app.Workbooks.Open(dataFilePath)
If Err.Number <> 0 Then
Call reportError
End If

' I would prefer to type the more dynamic: app.Run macroName, inputFilePath, dataParam1

app.Run "literalMacroName", "literalInputFilePath", "literalDataParam1"
If Err.Number <> 0 Then
Call reportError
End If

This is not the correct way of using the Run Method

app.Run "literalMacroName", "literalInputFilePath", "literalDataParam1"

Would Be more correct.

app.Run "literalMacroName"& "literalInputFilePath"&"literalDataParam1"

VBS Run Method

Problem 1
If you are trying to pass varibles make sure these exists in your script, the below
would only be process as string. They would not be process as Varibles.

"literalMacroName", "literalInputFilePath", "literalDataParam1"
